I am new to SSL-mechanism of qmail server.
It seems that we have two choices to do that:
(1)use stunnel
    stunnel can listen a specific port and unencrypt the
   encrypted packets and redirect to standard port.
   stunnel do the "listen and decrypt"task well.
 
  But how to send out mails encrypetd by stunnel?
 
(2)use tls.patch
    This patch can patch the qmail-smtpd and qmail-remote.
    But if some mail server which isn't able to speak SSL,
    what will qmail-smtpd process this case?
 
   And what will qmail-remote do if it send a mail to
   non-SSL mail server.?
 
  Should I read RFC2487 to get knowledge in detail?
 
  Might someone give me a hand?
